HOlSTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 266,149, dated October17,1882.

Application filed February 20, 1882. (No model.)

To all whom it may concern Be it known that I, ARTHUR HENDEY, a citizenof the United States of America, residing at Denver, in the county ofArapahoe and State of Colorado, have invented certain new and usefulImprovements in Hoisting-Machines, and I do hereby declare the followingto he afull, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters or figures of reference marked thereon, which lOlIll a part ofthis specification, and in which Figure 1 is a plan. Fig. 1 is anenlarged vertical longitudinal section taken on the line or of Fig. 3.Fig. 3 is an enlarged horizontal cross-section taken upon the line to wof Fig. 2, the engine and frame not being shown. Fig. at is an enlargeddetached View of the outer collars and their operating devices. Fig. 5is an enlarged view of shaft cap and nut. Fig. 6 is an enlargedcross-section taken upon the line 3 yof Fig. 3, showing outer collar,hub, groove and feather, hollow shaft, and rod in section. Fig. 7 is anenlarged .inside elevation of one of the friction-wheels, with thehollow shaft shown in section taken upon the line a a of Fig. 3. Fig. 8is an enlarged view of the shaft, showing the feathers and part of theend broken away, exposing the rod. Fig. 9 is an enlarged isometrioalprojection of the collar. Fig. 10 shows isometrical projections of thetwo outer collars, part ofone of which is broken away to show itsinternal construction. Fig. 11 is an isometrical projection of the nutfor the rod. Fig. 12 is an isoinetrical projectionf of one of the endcaps. Fig. 13 shows isometrical projections of the steel pin and.roller. Fig. 14 is an isometri-cal projection of the key 0, for lockingthe nut 11 to the rod cl.

My invention relates more particularly to that class ofhoisting-machinesin which a load is lowered or elevated by a line whichis wound around a drum that is operated by a steamengine or othersuitable power; and it consists of a drum, friction-wheels, and certainother novel mechanical combinations and arrangements, which I will nowproceed to describe, and point out particularly in the specification andclaims.

A represents an engine, ot'any suitable form and construction forfurnishing the required power, anti B the frame upon which the engineand hoisting-machine rest.

0, D, E, and F are the standards that sumtain the bearings for theshafts G and H. The shaft G carries a balance-wheel, I, and a pinion, J,that engages with the gear K, through which the power of the engine istransmitted. The gear K has a hub, L, and is mounted upon the shaft H,to which it is secured bya feather, M, which permits the requiredmovement lengthwise of the shaft to which it transmits the power oftheengine. The shaft lil is hollow from end to end, and is seated in abearing on the standard O at one end, and is inclosed within a collar,N, at the other, within which it revolves. The collar N is seated in abearing upon the'standard E, to whichitis secured and held by twoset-screws, O O, and is connected to the hub L of the gear K by an outercollar, P, which is secured to the collar N by means of two steel pins,Qand Q, that are secured to the collar and provided with antifrictionalsleeves R and It, fitted in diagonal slots S andS, and secured to thehub I1 by means of an end cap, T, set in a groove, U,

near the end of the hub and bolted to the end of the outer collar,permitting a free revolution of the hub, but controlling its movementlengthwise. An inner flange, V, extends inward and sets against the endof the hub. the opposite end of the collar N an outer collar, \V, issecured, in the same manner as the outer collar P, by'steel pins X andX, secured to the collar N, and provided with anti-frictional sleeves Yand Y, passing through diagonal slots Z and Z. The outer collar \Vpasses beyond the end of the collar N, and is provided with an internalflange, (1, against which a round nut, l), is screwed down on the rod d,and secured by a key, 0. A cap, 0, covers the projecting flange f ofcollar W and the outer rim of the nut I), thus making between the cap 0and the internal flange,a, achamher in which the nut b is confined, butallowed a free revolution.

The frictional wheel 17 is of suitable diameter, and has a hub of anyrequired length to se cure a proper bearin g upon the shaft H, uponwhich it moves, controlled by the splinej.

g is a pin passing through the rod d, and through the slots h and h inthe shaft H, the

ends of the pin being fastened in the hub of the frictional wheel i, theslots h and it allowin g the lateral movement of the friction-w heel i'.This wheel has a face, 7c, of any required breadth to receive africtional band, l, of any suitable material, preferably of paper-pulp,cut in rings of suitable diameter, and clamped against the projectingflange m by bolts a and a ring, 0. The face of the frictional band I isbeveled to meet the internal beveled frictional surfacep at one end ofthe drum q. The drum q is provided with hubs 1' and s, and revolvesfreely upon the shatt H, being held in place by the collars t and a,which are held to the shaft by set-screws, as shown in Fig. 3 of thedrawings.

The gear K isprovided with a frictional wheel, a, secured to its radialarms, preferably cast of the same piece of metal; but, if desired, itmay be constructed separately and secured to the gear in any desiredmanner. Like the frictional wheel 1, the frictional wheel 1* is facedwith a frictional band, 10, clamped to the projecting flange m by meansof a ring, 3 and suitable bolts, This band is beveled to meettheinternal beveled frictional surface, A, at the brake end of the drum(1. The drum (1 is provided with a wire or other suitable rope, B, withoneend secured to thedrum and the other to a cage or other object to behoisted or lowered.

To the under side of each of the outer collars, P and V, dependent arms0 and D are bolted or otherwise suitably secured, and are connected witheach other and a lever, E, by a fork, F, the fulcrum of the lever beingat the outer end of a bar, G, of suitable length, secured to thestandard I The end of the bar G is forked, and between these forks thelever E is held by a bolt passing through the ends and the lever.

A brake is provided for the drum, convenient for the operator, byconstructing a groove, H, on the outside of the end flange of the drumnext the gear, in which a strap, 1, is placed and secured to alever, J,pivoted upon the frame beneath the groove at K. The lever J has a shortarm, L, projecting upward from the pivotal point, to which one end ofthe strap is secured, the opposite end of the strap being secured to thelever J, at a suitable distance from the fulcrum, by a screw-threadedrod, M, bolted to the lever and passed through an eye, N, secured to theend of the strap, where it receives a nut by which the slack of thestrap is taken up. The lever J extends back any suitable distancerequired to obtain the necessary power, and terminates in a slotted end,0, that receives a bolt connecting it with the arm P of the lever Q",that is pivoted at It, and provided with a pawl for engagement withnotches on the stand S" for holding the lever. By this brake themovement of the drum is controlled by the lever Q, without otherassistance, and it is designed to use this brake alone in lowering thecage or other thing by reason of gravity.

In operating this hoisting-machine the engine is kept running forwardand never reversed. When hoisting a load the lever E is drawn outward,thereby throwing in the fork F and revolving the outer collars, P and\V, around the collar N, which are respectively thrown to the left andright for a distance, say, of half an inch, by means of the pins Q andQ, and slots S and S. The outer collar 1 forces the hub L along theshaftll, thus carrying the gear K to the let't from the position shown bydotted lines in Fig. 3 of the drawings, and bringing the face of thefrictionwheel 0) in contact with the frictional surface. A of the drum.At the same timeand by the same movement the outer collar \V forces thenut b outward, thereby drawing the rod (1 through the hollow shaft II,moving the ping laterally toward the right in slots h and h, and drawingthe wheel 17 from the position shown in dotted lines in Fig. 3 of thedrawings into contact with the frictional surface of the drum, thusclamping the drum between the frictional wheels I. and c, which receivemotion from the gearK. To reverse the movementof the drum and lower aload, the operator, with one hand on the lever Q}, tightens theln-ake-strap, and at the same time with his other pushes in the lever E,thereby withdrawing the frictionalwheels from conIact with the drum.Gravity here asserts itself, and the descent of the load is controlledby the brake.

For the purpose of taking up the wear of the frictional surfaces of thedrum 1 and frictionwheels i and r, the end of the rod (1 is providedwith one or more grooves, s, and the nut I) with four grooves, 1, 1 If,and t, so as to permit of an adjustment of a quarter-turn of the nut onthe rod d. In taking up the wear the collars t and a are loosened andthe drum forced up against the friction-wheel r and the collars set. Thenut 71 is then screwed up on the rod (1, thereby drawing thefriction-wheel i to therequired position, which being attained, and thegrooves of the rod and nut brought to a register, the key 0 is insertedin the grooves and held in place by a screw, r passing through the headof the key into the lint I).

Having thus described my invention, I claim as new and desire to secureby Letters Patent-- 1.
